About Middleware
Foundational middleware technologies are designed to facilitate distributed computing, though they differ significantly in architecture, scope and standarization. DCOM(Distributed Component Object Model ), introduced by Microsoft, is a binary-standard, Wnidows-centric technology that enables communication between component using Object Remote Procedure Calll (ORPC) and relies on the Service Control Manager(SCM) for object activation and location. It supports multiple interfaces per object via IUnknown but does not support multiple inheritance, relying instead on QueryInterface for navigation.
